Abstract
V diplomski nalogi smo na treh lokacijah (Ljubljana – Obrije, Dekani, Duplek – Johe) pridobili vzorce zemlje in česna dveh sort (´Garpek´ in ´Gardos´). Vzorce česna smo razdelili na štiri morfološke dele rastline: korenine, zeleni del, ovoj stroka in strok česna. Rezultate vsebnosti kadmija (Cd) smo primerjali med različnimi rastlinskimi deli in jih vrednotili glede na mejno vrednost za živila. Ugotavljali smo, kaj vpliva na sprejem Cd v rastlino in na katerih lokacijah je bila mejna vrednost za Cd v rastlini presežena. Primerjali smo tudi sprejem Cd glede na sorto česna. Ugotovili smo, da večja koncentracija fosforja in organske snovi v zemlji negativno vpliva na sprejem Cd v rastlino. Ugotovili smo tudi, da se koncentracija Cd v rastlini razlikuje po morfoloških delih rastline. Vsebnost kadmija v česnu se je razlikovala po lokacijah. Mejno vrednost za živila je v ovojih in koreninah presegala na vseh lokacijah obeh sort, v zelenem delu in strokih je bila mejna vrednost presežena le v Dupleku – Johe in Ljubljani – Obrije. Vsebnost Cd v sorti ´Garpek´, je bila v povprečju večja od vsebnosti v vzorcih sorte ´Gardos´, kar lahko sklepamo, da na sprejem vpliva tudi sorta česna.

Title:The content of cadmium in different parts of two varieties of garlic (Allium sativum L.)
Abstract:
In the diploma thesis, we obtained soil and garlic samples of two varieties ('Garpek' and 'Gardos') at three locations (Ljubljana - Obrije, Dekani, Duplek - Johe). Garlic samples were divided into four morphological parts of the plant: the roots, the green part, the tunic of the bulb and the cloves of the garlic. The results of the cadmium content (Cd) were compared between different plant parts and evaluated against the maximum level for foodstuffs. We determined what affects the uptake of Cd into the plant and at which locations the threshold for Cd in the plant was exceeded. We also compared Cd uptake by garlic variety. Higher concentrations of phosphorus and soil organic matter were found to have a negative effect on the uptake of Cd by the plant. We also found that the concentration of Cd in the plant differs according to the morphological parts of the plant. The Cd content of garlic varied by location. The limit value for foodstuffs exceeded in all samples of tunics and roots at all locations for both varieties, in the green parts and in the cloves the limit value was exceeded only in Duplek - Johe and Ljubljana - Obrije. The Cd content of the 'Garpek' variety was, on average, higher than the content of the 'Gardos' samples, which suggests that the acceptance of the garlic varieties was also affected.
